The cranch squid lives in the Northern Atlantic and has photosphores in its eyes which allow it to see in the depths of the ocean to catch their prey. The females can grow to be 40 cm, but their transparent bodies make them incredibly difficult to see. While they are able to squirt ink to avoid predators, they are also able to suck their tentacles inside of them and fill themselves with water to form a large ball.
